Overview for the Sokkia DT940L 9 Second Digital Theodolite with Laser Pointer

The Sokkia DT940L Digital Theodolite has a built-in coaxial laser pointer that maximizes efficiency when taking precise angle measurements. With 9-second accuracy, absolute encoder, tilt sensors, 26x magnification and 3-inch telescope resolving power, this optical instrument provides exceptional viewing quality of points and long working hours, making it ideal for layout and general construction applications.

Long-Range Laser

With a working indoor range of up to 660 feet, the DT 940L’s laser pointer guides surveyors during alignment, layout, leveling, grading and squaring. This visible laser also enhances outdoor aiming, while the ultra-narrow beam precisely measures through walls, corners, fence openings and tree branches.

Reliable Measurements

By using advanced algorithm and digital sampling technology, the integrated absolute encoder automatically restores the azimuth when the instrument is shut down or restarted to save time.

Various Display Modes

Select the angle display unit that best suits you. Horizontal angle is switchable between clockwise and counterclockwise, angle hold and zero-set functions are also provided.

Sound Notification

Once the zero horizontal angle direction is determined, the DT940L survey instrument produces audible tones for each of the four right-angle directions. It sounds two different tones within ±15 degrees of 90 degrees and stops beeping when it comes within ±1 degree.

Easy to Use Control Panel

This Sokkia electronic theodolite features a large LCD screen that provides clear angle reading, while its integrated four-key operation offers a short learning curve for beginners.

Ultra-Long Working Hours

The Sokkia DT940L boasts an IP-66 rating for protection to dust and water resistance. It also uses four AA alkaline batteries for up to 170 hours of operating time and works for two to five weeks without changing batteries depending on usage.

This Sokkia theodolite package comes with a hard carrying case, lens cap, plumb bob, tool pouch, vinyl cover, cleaning cloth, batteries and 1-year manufacturer’s warranty.
